From the foregoing description it will be seen that the primary purpose of the invention is to provide means permanently connected with the car radiator and preferably below the same, by which when the car is to be left in the garage, the said means may be instantly connected with a lamp socket and the water in the radiator heated thereby. It is of course obviousthat the necessary current might be obtained from sources other than a lamp socket, such for instance as a storage battery forming part of the equipment of the utility of the device would be extended to street use and available at any time or place at which the car might be standing and the engine stopped. It is further obvious that-connection with the radiator of an automobile is by no means the only field of usefulness for the device, many other applications of the device will readily occur to persons skilled in the art to which it appertains, as also minor variations and changes in the details of construction of the various parts and the combinations of the of course claim as mine I all such changes and variations as could be j rightfully considered as coming within the spirit of the invention or within the scope of the appended claims.
